The City of Baguio (Ilokano: Ciudad ti Baguio; Filipino: Lungsod ng Baguio) is a highly urbanized city in northern Luzon in the Philippines. Baguio City was established by Americans in 1900 at the site of an Ibaloi village known as Kafagway. Baguio City was designated by the Philippine Commission as the Summer Capital of the Philippines on June 1, 1903.The name of the city is derived from the word bagiw in Ibaloi, the indigenous language of the Benguet Region, meaning 'moss'. The city is at an altitude of approximately 1500 meters (5100 ft) in a moist tropical pine forest conducive to the growth of mossy plants and orchids.

The region around Baguio was first settled by the Cordillerans, primarily the Kankane-y, Ibaloi, and Itogon tribes. In nearby La Trinidad, Spaniards established a commandante or military garrison, although Kafagway, as Baguio was once known, was barely touched. In 1901 Japanese people and Filipinos commanded by the Americans in engineering built Kennon Road, the first road directly connecting Kafagway with the lowlands of Pangasinan. Before this, the only road to Kafagway was Naguilian Road. On September 1, 1909 Baguio was declared a chartered city.
